I recently ran across this version of the Deetail German BMW bike. According to the seller, this was an earlier and apparently less common version than the dark grey model. There are a few other differences in the design of the bike, like the muffler for instance and the fact that the engine is a different color. The rider seems to be the same.
Here is a simple two man team with a boat ready to attempt an amphibious crossing. The boat does not look like much, but having an engine it provides a big advantage over having to row while dodging bullets. On the downside, with that engine it would not be of much use for a surprise/stealth crossing. Coming to think of it, I think the figures are quite a bit nicer than the actual boat.
Britains Deetail 105 mm Pack Howitzer - Part I
From what I have researched, this looks like the Post-WWII Oto Melara 105 mm Pack Howitzer. Developed in the mid 1950's for the Italian Alpine troops. It could be disassembled into 12 separate components which could then be put on mules capable of dealing with the mountainous terrain. This version of the Deetail Howitzer comes with a movable trail which can be pulled apart when deployed.

Here is another version of the 105 Pack Howitzer. This one comes with a collapsed, non-movable trail. It also has a spring-based firing mechanism. This howitzer could also be transported by having a small vehicle tow it. The Oto Melara became quite popular, being used by over 30 countries, with 20+ nations still using it today.
